I've not seen any recognizable benefit in heeding that warning, but YMMV I've two Pi2's with 3.6G of swap and one with 1.7G of swap. All misbehave in the same way. If using USB you could try something like (as root) swapoff /dev/da0s2 gpart resize -i 2 -s 1700M /dev/da0s2 swapon /dev/da0s2 If using microSD I'd be wary of swap; some very mysterious file corruption emerged on a Pi3 which had swap on the microSD. Not your situation, of course, just a cautionary tale. FWIW there is a random collection of "notes to self" at http://www.zefox.net/~fbsd/ It's poorly organized, out of date and at least partly wrong. HTH, bob prohaska >home | help
